Comparison of Outcome of Decompressive Craniectomy with Wide Dural Flap Duraplasty Versus Dural Slits in the Management of Post Traumatic Acute Subdural Hematoma in Terms of Postoperative CSF Leak
Keywords:Decompressive craniectomy, acute subdural hematoma, CSF leak
Objective: To compare the frequency of postoperative cerebrospinal fluid (CSF) leak after decompressive craniectomy with wide dural flap duraplasty versus dural slits in patients with post traumatic acute subdural hematoma.
Material and Methods: The study was conducted from August 2017 to February 2018 in the Department of Neurosurgery, PIMS, Islamabad. A total of ninety-two (n = 92) adult patients of either gender between age 15-55 years presented with isolated, unilateral traumatic acute sub dural hematoma (ASDH) with midline shift of 5mm were categorized into 2 groups; Group A (DC with open dural flap) and Group B (DC with dural slits). Patients were observed for CSF leakage for four weeks.
Results: Results showed that the overall frequency of CSF leak was not significantly different in both groups and revealed that the CSF leak was observed in 10.9% (n = 5/46) in group A (DC plus open dural flap) and in 21.7% (n = 10/46) in group B (DC plus dural slits) (P = 0.158). The difference was not significant in terms of frequency of CSF leak in both groups when results were stratified with respect to gender, age, duration of trauma and baseline GCS. P value (chi-square) was found to be > 0.05 in all cases.
Conclusions: The postoperative CSF leak was observed in higher percentages in patients who underwent DC with dural slits as compared to the patients who underwent DC with open dural flaps for surgical management of ASDH. The difference, however, was not statistically significant.
